REVERSING-GEAR.

SPECIFICATION forming part of Letters Patent No. 663,372, dated December 4, 1900.

Application led March 12, 1900. Serial No. 8,837. (No model.)

To (1J/Z whom, t may con/cern:

Be it known that we. VILLIAM WY. TUCK, a resident of New York, borough of Brooklyn, county of Kings, and AUGUST WASSMANN, a resident of New York, (Astoria,) borough of Queens, county of Queens, State of NewYork, citizens ofthe United States of America, have invented an Improved Reversing-Gear, of

which the following is a specification.

The object of our invention is to construct a simple and efficient reversing-gear such as shall be specially applicable for use on powerdriven launches, automobiles, dac.

In the accompanying drawings, Figure l is a longitudinal section of our reversing-gear. Fig. 2 is a plan view of part of the same on a scinewhat-larger scale. Fig. 3 is a view looking in the direction of the arrow l, Fig. 2; and Fig. 4C is an enlarged sectional View looking in the direction of the arrow 2, Fig. 2.

ln the particular construction of our in ven tion illustrated in the drawings the arrangement of shaftingis such as would be used in applying the gear to a power-driven launch; but it will be understood that our invention may be applied to other arrangements of shafting.

ln the present instance,A is the driven shaft, to which rotary motion is appliedfrom the motor, and Z is the shaft to be driven in one direction or the other. This driven shaft Z is shown as provided with a bearing at X, while at the inn-er end z' it finds a bearing within the end of the driving-shaft A, but in such a way that the driven shaft Z can have a short longitudinal motion imparted to it by any suitable means, as through a lever F, pivoted at f to a bracket on a fixed framework G, this lever F act-ing on a collar z, pinned or otherwise secured to the shaft Z.

To the end of the driving-shaftA is secu red, by means of a nut a or otherwise, an inclosing casing consisting of awheel B and a cylinder B', inelosing the gearing, hereinafter described. The wheel B and casing B have opposite internal conical friction-surfaces b and b. Working in conjunction with these two conical clutching-surfaces are two friction-disks C and C', carried hy and free to move endwise or longitudinally with the movement of the shaft Z, so as to bring the disk C into frictional engagement with the surface b or to bring` the disk C' into frictional engagement with the surface b', the

other disk being in each case free f rom en- `gagement with its frictionsurface. Of these two clutching-disks one (marked C) is shrunk onto or otherwise firmly fixed to the shaft Z, so as to rotate with it, while the other disk, C', is free to turn upon a sleeve D, which in turn is loose or can rotate freely on this shaft Z, but is held endwise in posit-ion against the hub of the disk C by means of a suitable collar d. The two friction-disks C and C are geared together preferably through a pair of pinions 4 4, turning on radial pins 6, carried by the hub of the sleeve D, and meshing with bevel-wheels 3 and 5, secured to or formed in one with their respective disks C and C.

The sleeve D, which turns upon the shaft Z, extends out through an openingin the end of the casing B and has there secured to it, by means of keys e or otherwise, a brakewheel E, which thus lies adjacent to the opening in the end of the inclosed casing through which the shaft Z passes. We prefer to form a V-Shaped groove in the periphery of this brake-wheel E and to employ in connection therewith a pair of brake-levers H and H, hinged together at h, Figs. 2 and 3. One of these brake-levers H is hinged to the cranked or eccentric pin J, secured to a bracket on the frame by nuts in such a way thatit can be adjusted rotarily when necessary, Figs. 3 and 4. The corresponding end of the other lever H is connected by a link h' to a lever K, the pivot-pin of which passes through a Vertical slot in a bracket g on the frame. The connections of the brake-levers H H to the pin J and lever K are such as to allow lthe levers to move freely with the endwise movement of the shaft Z and wheelE,as shown l in Figs. 2 and 4. A set-screw le can be adjusted to act as an adjustable bearing-piece for the upper side of the pivot-pin lo as may be desired, for in the operation of the device when applying the brake-levers to the wheel E this pivot-pin 7a of the level' K will be forced up to a bearing against this set-screwr. As shown iu Fig. et, the left-hand end of the 1ever K is connected by a link m (set atan angle, as shown )to lugs on the operating-lever F. To the outer end of this lever F is connected a rod j' to move the driven shaft Z with its gear endwise in one direction or the other to reverse the motion. The parts may IOO are shown in the drawings when the shaft Z is to be disengaged from connection with the shaft A.

When the shaft Z is to be driven in the same direction as the driving-shaft A, the lever Fis operated to move the shaft Z endwise or longitudinally in the direction of the arrow 1,V Fig. l, to bring the disk C into firm frictional or driving contact with the wheel B. Under these conditions the shaft Z will be driven in the same direction and with the same speed as the shaft A. At the same time, the disk C being then free from contact with the surface b' of the casing B' on the shaft A, this disk C and the gearing will by simple friction run around idly in the same direction as and with the disk C.

When the shaft Z is to be driven in the opposite direction from that in which the shaft A is driven, endwise motion is imparted to the shaft Z in the direction of the arrow 2, Fig. 2, so as to free the clutch-disk C from the conical surface b of the wheel B on the shaft A and to bring the clutch C into engagement with the conical surface b of the casing l5. This same movement of the lever F, which has been employed to move the shaft Z endwise, will hold or brake the sleeve carrying the gear-that is, through the link m it will raise the corresponding end of the lever K, Fig. 4.-, and press its opposite end to cause the clamping-levers H and H to grip the brake-wheel E, and hence stop the rotation of the sleeve D. Then the connections between the driving-shaft A and the driven shaft Z will be through the casing B', disk C', bevel-wheel 3, pinions 4, bevel-wheel, and disk C, which is fixed to the shaft Z, and consequently this shaft Z will then be driven in the opposite direction to that in which the shaft A is driven.

The link m forms a species of toggle connection, so that in moving it over from the position shown by full lines in Fig. 4 to that shown by dotted lines to apply the brake the clutchdisk C will have full opportunity to make rm connection with the friction-face b' before the brake-levers are drawn home.

We claim as our inventionl. A reversing-gear comprising a drivingshaft and a pair of clutching members carried l thereby, in combination with a driven shaft,

said sleeve and intermediate gearing between the said disks and carried by the said sleeve.

3. A reversing-gear comprising a drivingshat't, an inclosing casing thereon and internal conical clutching members carried by the casing in combination with a driven shaft eX- tending wit-hin said casing and a pair of fric'- tion-disks carried by the driven shaft within the casing to engage with the said conical members, one of said disks being fast to the driven shaft and the other being loose thereon, intermediate gearing between the disks and means for braking or holding the said gearing. i

4. A reversing-gear comprising a drivingshaft, an inclosing casing thereon and opposite internal clutching members carried by the casing, in combination with a driven shaft, a pair of clutching-disks carried by the driven shaft within said casing, one of said disks being fast to the driven shaft, a loose sleeve on the said shaft, gearing carried by the sleeve between the disks and a brake-wheel also carried by the sleeve outside the casing with braking means for said wheel, substantially as described.

5. The combination of a driving-shaft and driven shaft and reversing-gear therefor with a brake-wheel for the reversing-gear, a supporting-frame, a pair of clamping-levers for the brake-wheel with an adjustable crank or eccentric pin for the support of one of the clamping-levers.
